I build production AI systems (RAG pipelines, AI agents, and LLM-powered SaaS) from architecture to deployment. Top-rated, with $15K+ earned and long-term clients who come back. Most AI projects stall between a working demo and a reliable product. Retrieval returns the wrong context, costs grow, outputs can't be trusted, and the codebase wasn't built to scale. That gap is where I work. I design systems where AI is part of the core architecture, and I own the full stack around it: backend, database, frontend, and infrastructure. 👉 What I build - RAG pipelines: chunking, embeddings, hybrid search, reranking, grounded answers - AI agents and LLM workflows that call tools, make decisions, and automate processes - Multi-tenant SaaS: auth, roles, billing, organizations, public APIs - Audits and fixes for AI systems with poor accuracy, latency, or cost 👉 Stack Next.js, React, TypeScript, JavaScript, Tailwind CSS · Node.js, NestJS, Express, FastAPI, Django, Laravel, Python · PostgreSQL + pgvector, Supabase, Neon, MySQL, MongoDB, Redis · Prisma, Drizzle · OpenAI, Anthropic, LangChain, n8n, RAG, AI Agents, Embeddings · Stripe, REST APIs, Multi-tenant SaaS · Docker, GitHub Actions, GitLab CI/CD, Vercel, Render 👉 How I work I understand the problem before choosing tools. You get clear communication, regular updates, and clean code another engineer can maintain. I'm in GMT+1 and available for fixed-scope builds or long-term work. If you need an AI system that works in production, not just in a demo, message me with what you're building.
